refractory cardiac arrest treated on field by ecmo

Conditions: Out-of-Hospital Cardiac Arrest; Extracorporeal Cardiopulmonary Resuscitation

Summary: out-of-hospital cardiac arrest without resumption of spontaneous circulatory activity despite advanced medical resuscitation is considered refractory. under certain well-defined conditions, today in many cities around the world and particularly in paris, it benefits from resuscitation called ecpr (extracorporeal cardiopulmonary resuscitation). this technique consists of the installation of an extracorporeal membrane oxygenation (ecmo) device allowing organ perfusion while waiting for a resumption of cardiac activity. since 2011, the paris samu (samu 75) has set up a team capable of implementing ecpr for refractory out-of-hospital cardiac arrests. this team based within the samu of paris at the necker hospital (ecmo team) composed of an emergency doctor or anesthesiologist-resuscitator, a nurse anesthetist and an ambulance driver intervenes in paris and its nearby region at the request of medical regulation. given the growing development of this activity, it is essential to measure its effectiveness in real-life conditions.

Eligibility criteria:
inclusion criteria: * all patients who have benefited from an installation or attempted installation of an extracorporeal membrane oxygenation (ecmo) device following a non-traumatic refractory cardiac arrest as part of the ecmo team of the samu de paris during the time of the study. * obtaining non-opposition from the patient or a relative in the event of the patient's death or a lasting state of health preventing them from becoming aware of the study. exclusion criteria: - minor patients
